I sell both Yamaha and Casio Privia products. I too am excited about the new touch screen Privia models but don't forget the Yamaha DGX650 is a $799 map great sounding digital piano/arranger that's been the best seller for over a year now. What the Privia has been lacking that Yamaha has over it are the quality of all the other voices, not just Pianos and the quality of the styles. Almost all the other features are equal but Yamaha has had a more intuitive operating system. I hope the new touch screen improves the awkward operating system of Casio's previous models. From the videos I've seen it should be a huge improvement but I still haven't heard many of the "other" sounds except the Pianos and only one modern style. I've been told everything has been improved but I will wait to be the judge when I receive my first units.
